Insects. 2115 



Crepidodera Modeeri. Plentiful in Newchurch Marshes, &c. 



Crepidodera rufipes. Also abundant in grassy places. 



Crepidodera Helxines, fulvicornis and cyanea. On sallows and aspens, in profu- 

 sion. These three (?) species, especially fulvicornis, are very variable in colour, as we 

 know, exhibiting shades of golden, bronze, green, purple, &c, and these variations 

 are not confined to the sexes uniformly ; sometimes the bronze male is attached to a 

 blue or green female, and vice versd, and sometimes both sexes are of the same colour ; 

 so that if these three be, as I suspect, but one species, it might deservedly be called 

 variabilis, in the fullest sense of the term. 



Thyamis tabida. On Senecio jacobsea ; a blood-red variety. 



Thyamis Jlavicornis. I captured this species rather plentifully on the Charlock, 

 in a ploughed field, near the spot where St. Catharine's lighthouse stands. It oc- 

 curred in May, 1845. 



Thyamis pratensis and apicalis. Not common, at least early in the spring. 



Thyamis ochroleuca. This species does not occur early in the season, but was 

 tolerably abundant in my garden, in the summer time, four or five years ago. 



Thyamis Ballotce. A very early and abundant species, on Ballota nigra in certain 

 situations ; for though the plant grows here in profusion, it is only in one or two spots 

 I find the insect. 



Thyamis dorsalis. This pretty species occurs very early, and in fact may be met 

 with all through the winter, on Senecio jacobaea, in warm sheltered spots, open to the 

 sun, and is pretty abundant in such places in March and April. 



Thyamis melanocephala. Common in herbage and moss. 



Thyamis atricilla. In meadows and grassy places, and from moss, but not abun- 

 dant in the spring. 



Thyamis thoracica. In the copses near Ryde and St. Lawrence, &c. 



Thyamis fuscescens, lurida and pusilla. The two last most abundant. 



Thyamis parvula. By sweeping the fine turf on the sides of the Downs : it occurs, 

 as usual, in company with Aphthona herbigradus, sparingly, in April. The two spe- 

 cies are generally found together, and I have taken them in similar situations, in 

 September, at Mickleham. 



Macrocnema Dulcamarce. By no means common, and apparently local. I have 

 taken about a dozen specimens, by examining the sunny sides of a stone wall, on warm 

 days early in the spring, where they appear basking and enjoying themselves, and evi- 

 dently prepared for a spring, so that it requires some address to secure them. 



Macrocnema Napi and erythrocephala. Occasionally on oleraceous plants. 



Macrocnema Spergula. Local, but in some plenty in the early spring of 1 846, 

 from February to April. I have not since met with it here. 



Macrocnema marcida. On Kakile maritima. 



Macrocnema affinis. I have taken only one specimen : it may possibly occur, as 

 the season advances, more freely. 



Mantura rustica and semieenea. I have only met with two specimens of each, and 

 they were shaken out of moss from a sandy common near Newchurch. None of the 

 species of Mantura occur, I believe, very early. 



Mantura obtusata. On the dwarf Cistus, in chalky soils, in April, 1848, sparingly; 

 but it will probably occur more plentifully as the season advances, for I took it on the 

 Gogmagog hills, near Cambridge, at the beginning of June.
